“It must certainly be admitted, then, that Christianity does depend upon something that happened; our religion must be abandoned altogether unless at a definite point in history Jesus died as a propitiation for the sins of men. Christianity is certainly dependent upon history. But if so, the objection lies very near. Must we really depend for the welfare of our souls upon what happened long ago? Must we really wait until historians have finished disputing abut the value of sources and the like before we can have peace with God? Would it not be better to have a salvation which is with us here and now, and which depends only upon what we can see or feel?

“With regard to this objection it should be observed that if religion be made independent of history there is no such thing as a gospel. For “gospel” means “good news,” tidings, information about something that happened. A gospel independent of history is a contradiction in terms. The Christian gospel means, not a presentation of what always has been true, but a report of something new–something that imparts a totally different aspect to the situation of mankind. The situation of mankind was desperate because of sin; but God has changed the situation by the atoning death of Christ–that is no mere reflection upon the old, but an account of something new. We are shut up in this world as in a beleaguered camp. To maintain our courage, the liberal preacher offers us exhortation. Make the best of the situation, he says, look on the bright side of life. But unfortunately, such exhortation cannot change the facts. In particular, it cannot remove the dreadful fact of sin. Very different is the Christian evangelist. He offers not reflection on the old but tidings of something new, not exhortation but a gospel.

“It is true that the Christian gospel is an account, not of something that happened yesterday, but of something that happened long ago; but the important thing is that it really happened. If it really happened, then it makes little difference when it happened. No matter when it happened, whether yesterday or in the first century, it remains a real gospel, a real piece of news.
